<span>A zygote begins as a one-cell structure that is created when a sperm and egg merge.
In the embryonic development of people and different creatures, the zygote arrange is brief and is trailed by cleavage, when the single cell moves toward becoming subdivided into smaller cells. we can also define zygote as a cell that is formed when two gametes meet.

The Yellowstone River ecosystem can support 2,300 bald eagles. This is an example of<u> temperate- zone ecosystems</u>

Explanation:

Yellowstone National Park is a natural  paradise with over 70 species of birds,which  include  trumpeter swans, sandhill cranes, loons, peregrine falcons, osprey and bald eagles

The Greater Yellowstone Ecosystem, with Yellowstone at its core, is one of the largest nearly intact temperate- zone ecosystems on Earth. It has an area of 12–22 million acres; 18,750– 34,375 square miles

<u>Temperate ecosystems are the ecosystem that are characterized by the  seasonality in temperature, with cooler winters and warmer summers, and also  show various  seasonality in precipitation patterns, resulting from seasonal changes in the orientation of Earth's axis relative to the sun.</u>

Which term best describes the difference in colors of the birds below?
NeX [460]

Answer:

<u><em>The correct option is C) genetic variation</em></u>

Explanation:

Genetic variation can be described as the differences present in the genetic material i.e DNA of organisms present in a population. Genetic diversity allows organisms of a species to better adapt to an environment. A population in which the genetic variability is scarce might become wiped out by a disease or an invading predator.

As the birds show different variations hence the term that best described them is genetic variation.

Explain how the data from your experiments showed that cyanide was used to poison Jared, and that 2-deoxyglucose, arsenic and ol
Aliun [14]

The question is incomplete as the background of the case and symptoms of Jarod is not provided, however, the missing data required for the question is as follows:

Jared was investigating a drug cartel and ate a meal with one of the suspects. After the meal, he had trouble breathing and felt weak and dizzy. Jared may have been poisoned. He is being taken to the CIA hospital for treatment. You are a medical toxologist working for the CIA. It is your job to find out what poison was given to Jared and try to save his life. Patient: Jared Sondheim Age: 32 Occupation: CIA Agent Symptoms: Muscle Weakness Shortness of Breath Dizziness. Jared has arrived at the hospital! It is your job to find out what toxin was used to poison Jared. You can then give him the correct antidote to save Jared's life.

Answer:

Poisning by 2-deoxyglucose syops the glycolysis process which leads to cardiovascular and respiratory symptoms. Due to property of inhibiting the enzyme reqquired for glycolysis, glucokinase. So, there is no ATP production takes place.

Arsenic poisoning inhibits the second stae of cellular respiration, the Krebs cycle which leads to pyruvate accumalation. The symptoms associated with arsenic are diarrhea, sking tone, abdomunal pain, and muscle cramps.

Oligomycin is used as an antibiotic to inhibit proton ATPase present in mitochondria membrane which blocks ATP formation. Watery eyes, cough, congestion in chest and nose are sysmptopms of oligomycin poisining.

The symptoms cyanide poisoning are dizziness, short breath, nd muscle weakness which matches with the symptoms of jarod.

In muscle cells, fermentation produces _____.
algol13

Answer:

The correct answer is E. Lactate and NAD+

Explanation:

Fermentation occurs in anaerobic condition and in humans, most of the energy is provided by aerobic respiration but when the body needs a lot of energy in a very quick time like in sprinting then muscles use lactic acid fermentation to gain energy.

After the consumption of all stored ATP during intense work, our body starts lactic acid fermentation to gain ATP. In lactic acid fermentation, the pyruvate molecule that was produced during glycolysis is converted into lactate molecule. In this process, NADH is oxidized to NAD+.  

Therefore in lactic acid fermentation lactate and NAD+ are produced. So the correct answer is E.

Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain protei
valkas [14]

Answer:

From the given information, the transport of glucose in blood across the red blood cells takes place by facilitated diffusion, that involves the spontaneous passive-transport with the help of trans-membrane proteins or transporter proteins to move the ions or molecules down the concentration gradient.

While the transport of glucose in intestines take place via active transport mechanism. It takes place from gut into intestines. It occurs against the concentration gradient with the help of energy molecules like proteins.
